We've hit the coldest stretch of the Hudson Valley winter so far. And we've all heard the saying from our parents at some point in our life; it's cold out, you're going to catch a cold! But is that really the case?

Scientists have long debated whether cold weather really causes people to get sick.

The LA Times reports a new study by researchers at Yale University believe that colder temperatures DO contribute to causing the common cold by lessening the ability of virus-fighting cells in our nose.

Basically in a warmer nasal cell, more interferons are released when a virus enters, increasing the likelihood that the illness can be fought off. In cooler nasal cells, the system is more inefficient leading to more chances the illness will spread.

So lock yourself indoors until spring. See you in March.
